Electric lock device with manual redundancy

Abstract

An electric lock operating in conjunction with a wireless remote transmitter and having redundant manual operation capability. The key lock cylinder has a three way position. In the remote position, the lock is enabled or disabled via a remote wireless transmitter. Operation of the wireless transmitter switch allows electric power to a micro switch that allows electricity to drive open a mechanical latch when a circuit is completed touching a pushbutton switch. In a manual lock position, the electronic function of the lock are disabled by mechanical discontinuity of a circuit preventing the latch from being opened either by electrical or mechanical operation. Turning the key in the lock cylinder to the manual open position will mechanically actuate the latch to open through a linkage system.
